Juliette Cornileau: Woman FIDE Master & Blitz Enthusiast

Known online as keopki, Juliette Cornileau has carved out a fierce reputation in the world of online chess, proudly holding the title of Woman FIDE Master. With a style characterized by gritty resilience and an uncanny knack for comebacks (a staggering 85.66% comeback rate, no less!), Juliette dominates the 64 squares with a blend of calculation and psychological warfare.

Rating Rollercoaster & Playing Style

Juliette’s peak blitz rating soared to an impressive 2266 in July 2024, showcasing her rapid tactical prowess and strategic mastery. Her bullet rating isn’t far behind, hitting a crisp 2092 in May 2025, proving she’s just as lethal under the ticking clock. Rapid games? She’s got those covered too, with a peak around 2069.

Her approach to blitz involves patience — she averages about 63 moves per win, suggesting she’s willing to outlast opponents in long tactical battles rather than relying solely on quick-fire attacks. Interestingly, she wins slightly more often when playing with the black pieces (48.26%) than with white (46.48%). A sneak peek into her psychological game reveals a modest tilt factor of 9, meaning even when the going gets tough, she keeps her cool — most of the time.

Opening Repertoire: A Secret Weapon

Juliette’s openings hint at a playful, yet solid repertoire. She plays a lot of “Top Secret” (read: unpredictable) moves – 270 games and counting – with a respectable 40.74% win rate in blitz. She doesn’t shy away from classic defenses, including the Caro-Kann (with an even 50% win rate), the Queen’s Gambit Declined, and the English Opening, all showcasing her well-rounded knowledge.

Battle-Tested: Recent Games

Her latest victory was a slick win using the Philidor Defense, forcing her opponent to resign after just 18 moves in a dramatic clash full of tactical fireworks. Even in defeat, Juliette keeps her head high — a recent loss came in a tense battle against a time scramble, reminding us that in bullet chess, every millisecond counts (and sometimes slips away!).

Did You Know?

  • She’s got an impressive longest winning streak of 10 games — a true streak of brilliance.
  • Despite the setbacks, Juliette remains a fierce competitor with a stubborn streak: her longest losing streak stands at just 9 games.
  • Her midnight owl tendencies are evident — the best time of day for her gameplay is precisely at 00:00 hours, when the mind apparently plays its best chess.

Whether facing down an unexpected gambit or carefully plotting positional dominance, Juliette “keopki” Cornileau continues to be a formidable name on the chessboard — both online and off. Watch out: she’s as quick with a joke as she is with a knight fork!

Hi Juliette!

You have a dynamic, tactical style that scores lots of quick wins—your miniature against awolknight (Bf7# on move 7!) is a perfect example:


What you’re already doing well

  • Tactical vision: You spot loose pieces and opportunities to win material (e.g. 15.Bxa8 vs mir1970).
  • Opening courage: Early central pawn breaks (d4/e5 ideas in the Philidor) show good fighting spirit.
  • Decisive finishes: When the initiative is yours you can convert very fast—see your high mid-game conversion rate on

    .

Key areas to improve

  1. Time management
    Five of your last six losses were on time. Bullet rewards intuition, but you are still spending ~4-7 s on many moves while opponents premove.
    • Build a reliable premove repertoire for obvious recaptures and checks.
    • Practice “chunking” positions in puzzles so decisions become automatic.
    • Play a few 3 | 2 games each day; the increment trains you to move faster without blundering.
  2. Early queen adventures
    Several losses start with Qh5/Qd5/Qb5+ (e.g. vs myominthant7048, lforssage). Against accurate defence the queen loses tempi and you fall behind in development.
    • Before moving the queen ask, “Will this force a concession or simply give my opponent tempo?”
    • Try the classic rule: Develop knights and bishops before bringing the queen out.
  3. King safety in the Scandinavian & Philidor
    Games with …Qd4 or …Qd5 left your king stuck in the centre. Review these openings from a model game and aim for quick castling.
    • For the Scandinavian, consider the solid 3…Qa5 line instead of 3…Qd4.
    • In the Philidor, remember the thematic break …d5 to free your position.
  4. Handling opposite-wing pawn storms
    Against the KIA loss to Kiron P Mullamkuzhi you advanced flank pawns without coordinating pieces, and the counter-attack hit first.
    • Follow the principle “Advance pawns on the side where you are stronger”.
    • Use prophylactic moves (h3, a3) before pushing major pawn storms.

Training plan for the next two weeks

  1. Daily 10-minute tactics set—focus on zwischenzug and forks (see fork).
  2. Play 20 bullet games, but annotate one each day. Look for a faster alternative in every move that took >3 s.
  3. Study one model Scandinavian and one Philidor game from a GM database; write the key move-order notes.
  4. Shadow-boxing drill: set a timer to 20 s and solve mate-in-2 positions—this builds speed without relying on premove.

Quick reminders

  • Use the opening tab on Chess.com to bookmark favourite lines—you’ll cut down early think-time.
  • Trust your instincts in bullet; if you feel unsure, move the safest piece to a safe square rather than hunting perfection.
  • Review every loss within 10 minutes while memories are fresh—particularly the critical moment where the evaluation swung.

Keep up the attacking chess, Juliette, and sharpen these practical skills—you’ll break your next rating barrier soon!
